Search result for publicphoto.org seem to be old watermarks and is likely to be read/crawl when google bot was not in allowed list (testing period). Current watermarks have them now URL and a QR-BarCode with real host-source.
Site has almost 25,000 pictures in hi-res format and in total there are about 100 thousand images, so it’s quite possible to see indexed images during testing, some strange with statistics on query written even in image ??
“googlebot” from htaccess covers all google bots:
– Mozilla/5.0 (compatible; Googlebot/2.1; +https://www.google.com/bot.html)
– Googlebot News
– Googlebot-Image/1.0
– Googlebot-Video/1.0
– *(compatible; Googlebot-Mobile/2.1; +https://www.google.com/bot.html)
except adsense bot:
– Mediapartners-Google
– AdsBot-Google (+https://www.google.com/adsbot.html)

About images uploaded via NextGen Gallery …
Plugin is designed specifically for use with native media uploader.
It is likely that the next-gen gallery do not follow the wp structure uploads and functions and make their own rules for attachments.
I study the problem when I have time, future version.
Now working on version 1.8.7 which will redirect clicks from BING, (in Firefox and Chrome) + logs referrer: filters and statistics to discover who is the most hotlinker, traffic in articles correlated with hotlinks, Who eats the most bandwidth, etc..
I have a lot of work for logs, but I promise to do my time for next-gen.
Personally I do not use plugins gallery, because I have my own plugin for displaying galleries, pagination, ajax, etc. see: https://mihella.me for xamples.
